Here’s what is great about Adam and Andy, they’re not only knowledgeable, fast and professional, but they do what it takes to get the job done well and at a reasonable price. Plus, they’re just really decent guys who take pride in their workmanship and their company. I felt like I could trust them and that they we’re making recommendations with my best interest in mind. I’ve referred Delta T to 3 other people since they completed work on my AC.


Delta T is very responsive, friendly, and knowledgeable. They are also honest and told us which system would be best for our house (which happened to be the lower-cost system). They didn’t try to upsell us! It’s so refreshing to find a company that cares more about its customers than the bottom line. And after the installation of our new AC and furnace units, they followed up and made sure everything was working well. We were so impressed with our experience that we switched our servicing to Delta T as well.


Our water heater quit working. A late evening call to Delta T provided next day service to assess the problem. They were able to install a new water heater with speed, efficiency and professionalism. They also installed an expansion tank to prevent any future problems. All hot water activities were restored shortly after our call to Delta T. We wholeheartedly recommend Delta T for any HVAC issues!! We never thought a new water heater could be such a beautiful sight!
Thank you Delta T!

I called Adam on a Saturday to give us a bid for AC replacement while receiving 4 other bids from big-name companies. We knew their reputation was good so we decided to give them a call as well. Came out Sat. afternoon to bid. Their bid was competitive and right for us. By Monday afternoon they had us up and running. Total install only took less than 4 hours and their work was top-notch quality.
First-class, genuine, local, guaranteed work! It will be our first and only call in the future.

After getting several estimates and talking with 3 other companies, it was clear Delta T was the right company to replace our aging furnace and AC unit. They offered a very competitive price but what really impressed me was Adam’s knowledge, attention to detail and desire to make sure the installation was perfect. I highly recommend these guys, you won’t be disappointed.

I own several rental homes throughout Johnson County and exclusively use Delta T to service and install at all my properties and my personal residence. Have referred them to several friends, family and coworkers without hesitation. Professional, efficient and always come through with high quality work at an affordable price.
